HINGE.

Application filed February 15, 1916.

To all whom it may concern:

Be it known that-we, NORMAN B. HURD and WILLIAM C. ROWE, citizens of theUnited States of America, residing, respectively, at New Britain andPlainvllle, Connecticut, have invented a new and useful Hinge, of whichthe following 1s a specification.

Our present invention relates to hinge generally and special objects ofthe invention are to prevent rotation of the hinge pin or pintle and tolock the pintle agalnst withdrawal when the door is in certain postions, as for instance, when the door 1s closed. In the accomplishmentof these objects we employ in a preferred form of the invention, meansin the shape of a washer non-rotatably held in a knuckle of one of thehinge leaves for preventing rotation of the pintle and means in theshape of a second washer carried by a knuckle on the other hinge leaffor preventing removal of the pin except in certain predeterminedpositions of the hinge leaves.

Other features and the details of construction will be understood fromthe following specification, attention being directed to the drawingforming a part thereof and wherein we have illustrated practical formsthe invention may take.

In this drawing :Figure 1, is a face View of a hinge constructed inaccordance with and embodying the invention. Fig. 2, is a sectional viewof the same taken substantially on the plane of the line 2-3 of Fig. 1showing also the upper washer and indicating the hinge in thedoor-closed position with the hinge pin locked against withdrawal. Fig.3, is a view on the same plane showing the hinge opened to a 90position, wherein the hinge pin is released and can be freely removed.Fig. 4:, is a perspective view of the several parts which constitutethis form of the hinge. Fig. 5, is a similar view of a slightlydifierent form of the hinge.

The two members or leaves of the hinge are designated 7 and 8, themember 7 in the illustration, being provided with a pair of hingeknuckles 9 and the member 8 with cooperating hinge knuckles 10, saidknuckles having a bore 11 therethrough to receive the pintle 12. Thepintle is secured against r0- tation by providing it with a flattened orSpecification of Letters Patent.

recessed portion 15 in one side thereof arranged to be engaged by aninwardly extending projection 16 on a washer 17 mounted in the caseillustrated in an annular seat 18 surrounding the bore in the lowermostknuckle 1.0 of the hinge leaf 8. This washer is nonrotatably held inthis seat by providing interengaging shoulders on the washer andknuckle, specifically illustrated as an outwardly projecting lug 19 onthe washer engaged between the shoulders formed by cutting a notch inthe edge of the annular seat, as indicated at 20 in Fig. 4. By locatingthis non-rotating washer in the lowermost knuckle, the hinge pin need beflattened only at the lower end portion thereof, specifically only onthe portion which projects into the lower knuckle. The securing of thehinge pin against rotation in this way produces a non-rising pin.

The hinge pin is locked against withdrawal by means similar to thenon-rotating means just described and consisting of a second washer 22seated in an annular seat 23 surrounding the bore in the lower knucklein the other hinge leaf and provided with an inwardly extendingprojection or lug 24: arranged to engage with transversely extendinglocking shoulders 25 on the pintle. This washer is held against rotationin its knuckle in a manner similar to the first washer by providing theinterengaging shoulders 26 and 27 on the washer and knucklerespectively.

In the construction illustrated, the nonrotating washer and the lockingwasher are mounted in the meeting upper and lower faces of the knuckleson the two hinge leaves and the recess in the side of the pintle extendsas far as the locking shoulders 25. It follows from this therefore thatwhen the leaves are turned so as to bring the looking projection 24 onthe upper washer and the non-rotating projection 16 on the lower washerinto the same plane as indicated in Fig. 3, the hinge pin can be freelywith drawn and that when the hinge leaves occupy a position such as thatindicated in Fig. 2 wherein the locking projection 2 1 overstands thelocking shoulder 25 on the pintle, the pintle cannot be withdrawn.

The parts are usually so arranged that the pintle will be locked againstremoval when the door is closed as indicated in Fig.

2 but can be freely Withdrawn when the H Fig. 5 is similar to the firstform illustrated except that in this case the non-rotating washer andthe locking Washer are of simi-' lar construction, the lockingprojection 24 on the locking .washer 22 corresponding as to shape to thenon-rotating projection 16 on the non-rotating washer 17. Also in thisconstruction the interengaging shoulders which hold the washers againstrotation are provided by forming the washers with spurs or outstandinglugs 30 which take into the metal of the knuckles as indicated at 31 inFig. 5 as the washers are forced into their seats. This construction hasan advantage over the first in that the cost is reduced by reason of thefact that both locking and nonrotating Washers may be made from the samedies.

What we claim is 1. Ina hinge construction, hinge leaves havinginterengaging knuckles a pintle engaged in said knuckles, a Washermounted in a knuckle of one of the hinge leaves, engaging shoulders onsaid knuckle and washer for securing said washer against rotation,engaging means on said non-rotating washer and pintle for'securing thepintle against rotation, a washer'carried by a knuckle of the otherhinge leaf, engaging shoulders on said knuckle and washer for preventingrotation of said washer in respect to said knuckle and engaging means onsaid second washer and pintle for preventing removal of said pintle.

2. In a hinge construction, hinge leaves having interengaging knuckles,a pintle engaged in said knuckles provided with a transversely extendinglocking shoulder and a recess in one side thereof, a washer nonrotatablyengaged in a knuckle of one of the hinge leaves and provided with aprojection engaging the recessed side portion of the pintle to therebysecure said pintle against rotation, a washer non-rotatably supported ina knuckle of the other hinge leaf and provided with an inwardlyextending proj ection engaging the locking shoulder on thepintleto'prevent removal of the same.

. 8. In a hinge construction, hinge leaves having cooperating knucklesprovided with a bore therethrough, washers seated in the meeting upperand lower faces of two of the knuckles on the respective hinge leaves,projections on said washers extending inwardly into the bore and apintle engaged in said bore having a recessed portion in one sidethereof receiving the projection on one of the washers and lockingshoulders extending transversely from said recessed portion arranged tobe engaged by the projection on the other washer.

4. In a hinge construction, hinge leaves having cooperating knucklesprovided with a bore therethrough, the lowermost of said knuckles havinga projection extending in wardly into the bore therein and the lowerknuckle of the opposite hinge leaf having a projection extendinginwardly into the bore through the same, a pintle engaged in the borethrough the knuckles having its lower end portion flattened at one sideto pass by the projection 'on the lower hinge knuckle whereby saidpintle is held against turning by said lower knuckle and said pintlehaving transversely extending locking shoulders disposed in the plane ofthe projection on the lower knuckle of the opposite hinge leaf to bethereby engaged by said projection and held against removal.
